execute ping
execute traceroute
 
Both should return the primary IP address for a given domain. It is assumed, that the FortiGate unit has a valid DNS configured.

Here is an example with mylabdomain.com , returning IP address 172.31.1.1

FGT # execute ping mylabdomain.com
PING mylabdomain.com ( 172.31.1.1 :( 56 data bytes
64 bytes from 172.31.1.1: icmp_seq=0 ttl=245 time=75.4 ms


FGT # execute traceroute mylabdomain.com

traceroute to mylabdomain.com ( 172.31.1.1 ), 32 hops max, 72 byte packets
1 172.31.1.1  0 ms 0 ms 0 ms
